Hi Alan,
I have no idea what's best, but I use a 4" angle grinder, and 
a die grinder with rotary files. Caution, BIG mess ahead. Eye 
protection, ear protection, and dust mask. Full bug. Don't 
have a strung piano uncovered anywhere in the vicinity either. 
Bass strings die in the presence of iron dust.
